MAX19997A Datasheet PDF - Maxim Integrated

●Description

●The MAX19997A dual downconversion mixer is a versatile, highly integrated diversity downconverter that provides high linearity and low noise figure for a multitude of 1800MHz to 2900MHz base-station applications. The MAX19997A fully supports both low- and high-side LO injection architectures for the 2300MHz to 2900MHz WiMAX™, LTE, WCS, and MMDS bands, providing 8.7dB gain, +24dBm input IP3, and 10.3dB NF in the low-side configuration, and 8.7dB gain, +24dBm input IP3, and 10.4dB NF in the high-side configuration. High-side LO injection architectures can be further extended down to 1800MHz with the addition of one tuning element (a shunt inductor) on each RF port.

●The device integrates baluns in the RF and LO ports, an LO buffer, two double-balanced mixers, and a pair of differential IF output amplifiers. The MAX19997A requires a typical LO drive of 0dBm and a supply current guaranteed below 420mA to achieve the targeted linearity performance.

●The MAX19997A is available in a compact 6mm x 6mm, 36-pin thin QFN lead-free package with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +100°C.
